Trillhaas Goetz. Innovations in Google and Global Digital TrendsVolha Banadyseva
Goetz Trillhaas discussed Google's 8 principles of innovation which focus on hiring great people, sharing ideas and information openly, having a clear shared vision while adapting, iterating products quickly, relying on data to drive decisions, and putting users first rather than money. He provided examples of Google's innovations like Google Search, Google Now, Project Loon for balloon-powered internet access, driverless cars, Google Glass, and Android Wear as well as their goal of giving users control.

This is a one slide presentation for the Haskell for Minsk conference that provides a link to view the full presentation on Google Presentations. The presentation discusses the Haskell for Minsk conference which is an event focused on the Haskell programming language and community in Minsk, Belarus.
The document discusses the present and future of metaprogramming in Scala. It describes scala.reflect, the current metaprogramming API, and its limitations. The future scala.meta API aims to have an independent language model, use hygienic quasiquotes for syntax trees, and make compiler syntax trees persistent. The new API design is being validated and will likely be available as a compiler plugin next year.
This document discusses a function-passing programming model for distributed systems. The key concepts are:
1. Immutable, stationary data stored in "silos".
2. Portable "spore" functions that are serialized and sent to remote silos to perform work on the data.
Silos contain the data and run functions on it. Silo references allow applying functions asynchronously across machines by serializing the functions and data references. The model aims to simplify distributed programming by keeping data stationary and moving functions to the data.
Сергей Сверчков и Виталий Руденя. Choosing a NoSQL databaseVolha Banadyseva
This document discusses choosing a NoSQL database for a project. It evaluated Couchbase, MongoDB, Riak, Cassandra, and MySQL based on performance benchmarks across various workloads and stability during node failures. Couchbase and Cassandra demonstrated the best performance and stability in most tests. MongoDB performance was impacted by availability of configuration servers. Riak and MySQL NDB Cluster were more complex to configure for geographic replication between data centers.
- Logistic regression is a classic machine learning algorithm used for classification tasks like predicting customer churn or click behavior. However, training logistic regression on large datasets ("big data") using the traditional batch approach is very slow.
- Online learning is an alternative approach that trains logistic regression on one data point at a time, allowing for faster real-time updates. Popular libraries for online learning include Sofia-ml, Vowpal Wabbit, and scikit-learn which can train models on data in batches.
- Expedia uses logistic regression for tasks like predicting hotel bookings and detecting credit card fraud, where billions of predictions are made daily. Online learning allows training these models faster to keep up with this scale
1. Adform has been researching technologies for Big Data analytics since 2012 as their data volumes grew to 1.4 TB per day.
2. They tested several technologies over 3 months each including IBM Netezza, HP Vertica, SAP Sybase IQ, Amazon Redshift, and Calpont InfiniDB to handle their needs for real-time queries, unlimited scaling, high performance, and no downtime.
3. While each technology had strengths, no single solution met all their requirements for queries, load speed, compression and more. Adform concluded the best approach is to adopt a technology based on your unique needs rather than forcing your needs to fit a technology.
This document discusses requirements for achieving operational big data at scale. It describes how advertising technology requires processing millions of queries per second for tasks like real-time bidding. It also outlines requirements for other domains like financial services, social media, travel, and telecommunications which need to support high volumes of real-time data and transactions. The document advocates for using an in-memory NoSQL database with flash storage to meet these demanding performance requirements across different industries.
This document discusses the journey of a company moving from a Microsoft-based infrastructure to using open source NoSQL databases like Cassandra and Aerospike to handle increasing data and performance needs. It describes initial experiments with Cassandra that showed promise but eventually led to performance issues as data and request volumes grew. An evaluation of Aerospike demonstrated significantly better consistent performance and simplified operations, leading to it replacing Cassandra in production. Lessons learned include regularly evaluating technology choices and being open to alternatives as needs change over time.
This document discusses counterfactual analysis using data from the search ads ecosystem. It describes how online experimentation using randomization allows for causal inferences about how auction parameters affect key performance indicators (KPIs), avoiding issues like Simpson's paradox seen in simple correlation analysis. The Cosmos and SCOPE systems are used to store and query the large ad auction logs and perform counterfactual computations in a MapReduce-like manner by reweighting past auctions. This allows estimating how the system would have performed under different parameter settings without actually changing the live system.
Ernestas Sysojevas. Hadoop Essentials and EcosystemVolha Banadyseva
This document provides information about Hadoop training delivered by DATA MINER, a training and consultancy company located in Vilnius, Lithuania. It introduces the trainer, Ernestas Sysojevas, and his qualifications. It then provides details about DATA MINER and its role as an exclusive Cloudera Training Partner in several countries. The document discusses the growing Hadoop market and increasing job trends related to Hadoop. It also briefly outlines the main roles involved in Hadoop like system administrators, developers, data analysts, data scientists, and data stewards as well as the typical skills and responsibilities of each.
The document discusses Adform's journey in exploring Hadoop as an alternative for main data storage and reporting. It outlines three aspects of their journey: direction/planning/equipment, travelling light to learn necessary skills like Java and Hadoop principles, and using commodity hardware despite challenges. The summary explores why Hadoop was considered, what skills were needed to be acquired, and issues faced with their existing hardware cluster.
